Which term refers to the long strands of DNA intertwined with protein molecules?

• A. Chromosomes
• B. Nucleus
• C. Cytoplasm
• D. Ribosomes

Answer: (A)

Understanding what chromosomes are: they are long strands of DNA intertwined with protein molecules called histones. This DNA–protein complex forms chromatin, which condenses into chromosomes during cell division to efficiently package and pass on genetic information. The nucleus houses the chromosomes but is not the strands themselves, while the cytoplasm is the fluid inside the cell outside the nucleus, and ribosomes are the protein-synthesizing machines. So the term that refers to these long DNA strands bound to proteins is chromosomes.
